United States Patent Patented Jan. 8, 1963 3,072,006 COVERS FOR SMALLORGANS R PIANGS Fred S. Jurkowski, 51 Ewing Road, McKees Rocks, Pa.Filed Aug. 8, 1961, Ser. No. 130,172 1 Claim. (Cl. 84183) This inventionrelates to new and useful improvements in covers for small organs orpianos that do not have built-in covers to protect the case andoperating mechanism from dust and dirt, and it is among the objects ofthe invention to provide a replaceable cover which shall be appliedbetween the end walls of a keyboard, the cover having a mounting bracketwith yielding engaging faces that will not mar the finish of the sidesof the keyboard.

It is a further object of the invention to provide such -a cover of adesign that it may be fabricated from fiberglass cloth or othermaterials and adapted to be rolled up and stored away when not in use.

The invention will become more apparent from a consideration of theaccompanying drawing constituting a part hereof in which like referencecharacters designate like parts, and in which:

FIGURE 1 is a view in perspective of a piano or organ keyboard coverembodying the principles of this invention;

FIGURE 2 is a cross-sectional view, partially in elevation, taken on theline 2-2 of FIGURE 1; and

FIGURE 3 is a transverse section taken along the lines 33 of FIGURE 1.

' In the drawings, the numeral l designates a tube of aluminum, plasticor other lightweight material provided.

at one end with a rubber tip 2 and with a telescoping tubular portion 3at the other end that is also equipped with a rubber tip 4. The tube 1is provided with a stop pin 5 against which a coil spring 6 rests, thecoil spring at its other end abutting the end of the telescoping tube 3.A stop pin 7 extends into a slotted portion 8 of the telescoping piece 3and the latter is movable into and out of the tube 1 a distancecorresponding to the length of the slot 8. A tube 9 of similar materialas the tube 1 and of the same dimensions lengthwise, is disposed in thecasing of a flexible cover, the casing being made by overlapping the end10 of the cover which is provided with a similar casing at its other endto receive the tube'l. The casings may be glued or cemented to the tubesto permanently fix their position against' axial displacement. As shownin FIGURE 2, the cover material may be split in the center and the tubes1 and9 may be terminated in the center and telescopically mounted over acentral tube 11 with which they have sliding engagement. The clothmaterial may likewise be provided with a splicing piece of clothdesignated by the numeral 12 in FIGURE 2 which overlaps the ends of thecloth sections, as shown,

so that the cover may be contracted and expanded to vary its width todifferent sized organs or piano keyboards.

In operation, the extensible end member 3 is'collapsed against thetension of the coil spring 6 and the rubber tip 2 is held against theend wall of a keyboard. The cover is then laid on the keyboard and themember 3 is released so that the rubber tip 4 engages the other end wallof the keyboard. The tension of coil spring 6 will firmly hold therubber tips 2 and 4 in gripping engagement with the end walls of thekeyboard. The end of the cover is then pulled over the keyboard andallowed to lap over the front end of the organ or piano to prevent dustentering into the keyboard. The cover cloth, which is generallydesinated by the numeral 10a, is then adjusted to the width of thekeyboard by adjustment of the telescoping tubing and the overlappingcloth portion 12. Once this adjustment is made, it is of course set forall time.

Although one embodiment of the invention has been herein illustrated anddescribed, it will be evident to those skilled in the'art that variousmodifications may be made in the details of construction withoutdeparting from the principles herein set forth. j

I claim: I p A snap-on cover for the keyboards of organs, pianos and thelike, comprising a flexible cover having casings provided at the endsthereof, a tubular member inserted in the casing at one end of saidcover having a slidable tubular member at one end mounted for telescopicmovement within said first-named tubular member and having a spring forbiasing the same to its extended position,

' said slidable member having a slot engaging a pin secured to saidfirst-named tubular member to limit its movement and said first-namedtubular member and telescopic tubular member having rubber tips forfrictionally engaging the sides of a'keyboard, a tubular structuredisposed in the casing at the other end of said cover member consistingof a central tube having a pair of tubular members in sliding engagementwith the outside of said central tube to be adjustable to the Width ofthe keyboard, said cover member having an overlapping portion of a widthto correspond to the distance of movement of said last-named slidabletubular members to adjust the width of the cover to correspond totheadjusted position of said tubular members.
